A more efficient engine, revised frame construction and heavier operating weight help the new Bomag BW284 tandem-drum vibratory roller meet Superpave project demands. Equipped with a 185-horsepower Cummins engine and an 84-inch wide drum, the unit features operating frequencies up to 4,000 vibrations per minute and a maximum working speed of 4.5 mph while delivering 10 impacts per foot. Centrifugal force ranges from 34,665 pounds in low amplitude to 41,235 pounds in high amplitude. Weighing 28,425 pounds, the BW284 is 7 percent heavier than the model it replaces, which improves compaction performance.
